Python Jupyter笔记本：连接到服务器时出错

我刚刚安装了最新的python版本（3.8.5）（Anaconda发行版），同时正确地遵循了文档中提到的所有步骤

然后我尝试使用以下方法将其添加到我的Jupyter笔记本中：

python -m ipykernel install --user --name=Python3.8.5

[Python 3.8.5是环境的名称]

我成功地将它添加到jupyter笔记本中

但当我试图使用Jupyter笔记本访问它时，它显示的是： jupyter notebook命令行中的回溯如下所示：

    To access the notebook, open this file in a browser:
